AGDE-E20 Overview

The AGDE, Altonics Genuine Digital Effect is Altonics’ newest line of high-quality/performance multi effects processors. Although many users of the AGDE-E20 will be looking for a solution for high-end multi-effectors or guitar & bass related sound processing, the wide range of effects provided by the AGDE-E20 is suitable for various applications including mixers, karaoke amplifiers and other sound enhancement products.

Instilled with Altonics’ about 20 years of know-how in digital sound processing, the AGDE-E20 provides the best audio quality and performance possible for whichever application you choose. With the Altonics name behind it, you know you can trust the quality of this audio signal processor.

The AGDE-E20 is an all-in-one effects solution. It supports filters that can be used for such as EQ, spatial effects such as delay and reverb, the whole range of modulation effects including chorus, flanger, phaser, wah-wah, tremolo, auto pan, vibrato and more. It also encompasses dynamics processing with a noise gate, compressor, and limiter. Fuzz, overdrive, and distortion are all provided in their full crunchiness while still maintaining crisp clear digital sound. Of course, a chromatic tuner can be provided. By real-time 32-bit digital processing, and you won’t need to look any further for all your sound enhancement needs.

In the following pages you will find our reference design implementing AGDE-E20’s functions to the fullest. Just pick the functions you want and match them with your custom control and display.
